- Registration Number
- NCT00577395
- Lead Sponsor
- Warner Chilcott
- Brief Summary
The purpose of this trial is to compare the difference in bone microarchitecture of the distal radius at month 12 in postmenopausal osteopenic women treated with risedronate 150mg taken once a month compared to placebo.

Group Intervention Description 1 placebo Placebo tablet once a month, orally 2 risedronate one 150 mg risedronate once a month, orally
- Primary Outcome Measures
Name Time Method Percent Change From Baseline in Erosion Index (A Ratio of Curve-like Structures to Plate-like Structures and is a Measure of the Degree of Structural Degradation) of the Distal Radius 12 months The percent was change from baseline in erosion index at the distal radius between the risedronate and placebo groups at Month 12 (the lower the percent change in erosion index, the greater the improvement of structural degradation); the last valid postbaseline measurement was to be used when the Month 12 value was missing (Last Observation Carried Forward or LOCF).
NOTE: The study was unable to recruit sufficient numbers of patients to meet with the protocol specified numbers, thus it was terminated early after 5 months. No efficacy analyses were performed.
- Secondary Outcome Measures
Name Time Method Erosion Index of the Distal Radius 6 months Study was terminated prior to acquiring any efficacy endpoints. No efficacy analyses were performed.
